A new research paper challenges the common belief that Vision Transformers (ViTs) inherently require more labeled data than Convolutional Neural Networks (CNNs) for industrial dense prediction tasks. The study suggests that the perceived data-efficiency gap is primarily due to pretraining incoherence between ViT backbones and CNN necks, rather than fundamental architectural limitations of ViTs. Researchers propose a novel AlignBlock to recalibrate features and demonstrate that with proper alignment, ViTs can outperform CNNs on domain-proximal datasets, while CNNs maintain an advantage in domain-distant scenarios.
